EasyRPG for Sega Dreamcast (Alpha release)

[Costenaro]

Ok, so the first game I converted to DC is "Os Cavaleiros do Zodíaco: Os Guerreiros Deuses de Asgard" name in portuguese or "Saint Seiya" in japanese.

And here I did a tutorial explaining the process to convert it (It's in portuguese):



And here is the CDI: https://drive.google.com/file/d/1i_IVvf ... sp=sharing

I'll try to take a look in the code to see if I'm able to make it save on the VMU, other than that, it is already working really well!!!

I'm sure RPG fans will appreciate being able to use this to bring over and create their own Dreamcast RPG games. Keep up the good work gameblabla.

It can already make use of 32MB.

Edit: To fix the audio, just convert the wav to 11025 hz.

Yes i did forget to mention that, there's currently no audio resampler and it's fixed at 11025hz.
That's what i did for Wadanohara as well.

Don't try to save, it's gonna crash for now.

I'm glad other people are playing around with it !

Minor update : Ghabry added minimal support for 16bpp and this time it doesn't crash...
I added another path that uses ARGB1555 and this allowed me to get into Wadanohara without the game crashing on me on real hardware (and the images do properly allocate this time).
Unfortunately the 16bpp path in Pixman is extremely slow, in spite of my attempts to make it faster.

Ghabry considered working on an implementation that doesn't rely on pixman but in the meantime i'm stuck with this (and i'm not really willing to fully switch to PVR api yet).

You can grab the build with this game if you wanna try :
https://github.com/gameblabla/EasyRPG_D ... s/tag/1.01

I also provided binary build still using the older, faster RGB24 path (but it eats more memory) :
https://github.com/gameblabla/EasyRPG_D ... es/tag/1.0

So you don't have to recompile EasyRPG for the binary, you can just reuse mine.

This is so cool, I'm going to try this one!

The CDZ game has been updated with the new BIN. You can download it on the same link!

Another update : Ghabry helped me track down the performance issues on the 16bpp build and it's a lot better now. It's now the default.

I also added MP3 decoding to the build and it only added like 100kb. I managed to save another 300kb or so by switching to Miniz/spng instead of libpng/zlib + some other changes. This shouldn't impact games for now (there's no transparency for png files using grayscale format for now but i've never seen a game use that).

Of course, you still need to convert all of your MP3 files to 11025hz, it goes without saying. (i may think of dropping the quality down to 8-bits but i'm not sure)

Anyway, i have provided new bins.
Save are still not supported btw, i encounter an issue with EasyRPG that just flat out crashes if i try to force set save_fs...
